Can you still get into an Ivy League school if you have a low SAT score but high IB points?

I’d hope. But apparently special allowances are made for special students. https://www.bostonglobe.com/metro/2018/07/28/how-you-get-into-harvard-for-lucky-few-there-list/68C5P12xK9advEpAC287aM/story.html

I don’t know if I’d call 1200-1280 extremely low test score… Cornell’s 25th percentile is 1330 which not too far off from OP’s score but I am sure that applicant had other hooks to make up for the low score - like being a recruited athlete, large donor, etc.
